JAMES READE, OF HUNTINGTON, NE \V YORK.

SPRAY-NOZZLE.

Application filed March 22,

To all whom "it may concem:

Be it known that I, JAMES READE, a citizen of Great Britain, resicling at Huntington, in the county of Sufi'olk and State of New York, have invented certain new and useful Improvements in Spray-Nozzles; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to spray nozzles, and has for an object to provide a nozzle embodying new and improved features of oonvenience, reliability and economy.

A further object of the invention is to produce a nozzle having a discharge orifice and with means interposed between the discharge orifice and the connecting hose adapted to produce a rotary motion of the water which, when discharged through the discharge orifice, will by centrifugal force expand into a conical spi-ay.

'With these and other objects in View, the invention comprises certain novel Constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the drawings: -Figure l is a view in side elevation of the improved spray nozzle showing in broken lines the cone of discharge. Fig. 2 is a sect-ional View diametrically of the nozzle. F ig. 3 is a plan View of the nozzle with the front cap removed. Fig. 4 is a view of the nozzle in front elevat-ion.

Like characters of reference designate corresponding parts throughout the several views.

The nozzle comprises a nipple 10 provided with means for connecting with the hose shown conventionally at ll and has secured to and communicating with such nipple a casing 12.

The casing 12 may be integral or perma- Specificaton of Letters Patent.

nently connected together and provided in its front wall 13 with a central orifice 14 l but preferably for convenience in manufacl ture and repair` and also to gain access to Patented Sept. 6, 1910. 1910. Serial No. 55o,9s1.

the casing the wall 13 is provided with a flange 15 which embraces the casing 12 and is connected therewith in any approved manner as by the screw threads as indicated at F ig. 2. The rear wall 16 may also be connected with the casing 12 by means of the fiange 17 and the screw threads as indicated. By this arrangement parts may be separated as desired.

Centrally of the casing 12 a diaphragm 18 is rigidly Secured being slitted radi-ally as at 19, wings 20 bent downwardly at an angle toward the rear wall 16. 'It will be apparent that the wings 20 are disposed at an inclination to the wall 16 and also to the diaphragm 18 and that when water is admitted to the rear of the diaphragm through the nipple 10 it passes outwardly and engaging the inclined wings 20 is discharged through the openings 21 and thereby given a rotary motion. The continued passage of water up the inclined wings 20 continues the rotary motion until the chamber above the diaphragm is filled when the water is forcedto pass through the discharge orifice 14, still in the rapidly rotating condition. As soon as it is dischargecl through the orifice 14: in such rotating condition it will be apparent that by cent'ifugal force the stream of water so discharged will be broken up into a spray as indicated at Fig. 1.

What I claim is A nozzle comprising a casing with a front and rear wall, a central diaphragm dividing said casing into two opposite compartments, the rear wall having a water inlet, and the front wall having a water outlet, said diaphragm having triangular portions all bent rearwardly from the diaphragm to provide wings and openings whereby liquid passing through the nozzle issues in spray form.

In testimony whereof I aiiix my signature in presence of two witnesses.

JAMES READE.
